Hey everyone,
I’m trying to figure out how to make Puppeteer download files when using headless Chrome. I know it can navigate web pages, but I’m not sure about saving actual files to my computer.
Does anyone know if there’s a way to tell Puppeteer to download stuff? Or maybe there’s a trick to making extra HTTP requests and grabbing the responses?
I’ve been googling for a while but haven’t found a clear answer. Any help or code examples would be awesome!
Thanks in advance!
I’ve found a reliable method for downloading files with Puppeteer in headless mode. The key is to use the ‘page.on(‘response’)’ event listener. This allows you to intercept network responses and save the file content directly. You’ll need to set up a custom download path and use the ‘fs’ module to write the file to disk. Additionally, make sure to configure Chrome’s download behavior using ‘page._client.send(‘Page.setDownloadBehavior’)’. This approach has worked well for me across various file types and websites. Remember to handle potential errors and check file integrity after download.
I’ve tackled this issue in my projects before. To successfully download files with Puppeteer in headless Chrome, you need to set up a custom download behavior. First, configure Puppeteer to use a specific download path, and then set up a handler for responses so you can intercept file downloads. You can trigger the download using the Page.evaluate() method and wait until the file is fully downloaded before continuing. Adjusting Chrome’s preferences to allow automatic downloads for certain file types might also be necessary. It took some trial and error, but this approach has proven reliable in my experience.
yo, i had this same issue! trick is to use page._client.send(‘Page.setDownloadBehavior’) to set the download path. then use page.on(‘response’) to catch the file download. you’ll need fs module to write it. works like a charm for me. good luck mate!
